BERT B. MONG, F MUNCIE, INDIANA, ASSIGNOR OF ONE-HALF TO EUGENE BROTHERTON, 0F MUNCIE, INDIANA.

VALVE FOR THE FUEL-NOZZLES OF INTERNAL-COMBUSTION ENGINES.

zen of the Fnit-ed States. and a; resident of Munci'e. in the county of Delaware and State of Indiana, have invented a new and Improved Yalvefor the Fuel-Nozzles of Internill-Combustion Engines, of which the followingis a full, clear, and exact descriptlon. Q 7

My invention relates to the nozzle of in ternal combustion engines, through which nozzle a liquid fuel is delivered with each stroke of the pump. n The prime object of my invention is'to provide a nozzle'of the indicated class having-valve means controlling the fuel feed whereby to insure the admission to the cylinde'r of a predetermined amount of fuel and;

the prompt and unfailing closure of the valve absolutely tight after the adnns's1on of the predetermined charge, whereby to obtain a more regular operation of the engine than is usual with the nozzles ordinarily employed.

A more specific object of the invention is to provide a valve of the class referred to of simpleform, and so constructed and arranged as to permit of the nozzle and valve being maintained in perfect working condition. v

The invention .will be particularly explained 111 the more specific description following. I

Reference is to be had to the accompanym'g drawings forming a part of this specification in which similar reference characters indicate. corresponding parts in all .they

views. v i I Figure 1. is a vertical section of a nozzle embodying my inventivm: Fig. 2 is a perspective vicw of one of the valve elements.

In carrying out my in ention in accordance with the illustrated example. a nozzle body 10 is provided having. at its upper end, external threads 11 for connection with the. fuel supply pipe-A. indicated by dotted lines. Fig. 1, said pipe in pra tice being cunncctcd with a pump. (not approvedmanner to deliver a t'lzar'gc of fuel with each stroke of the pump.- External threads 2 .are formed on the hody 10 to takainto t-he cylinder B. and an axial bore 13 is forni'cd through the'body for the pas-' sage of thefnel'. Alcap 14 is detachahly secured to the forward end of the body 10 Specification of Letters Patent.

adapted to close upwardly against aseat 1.7

on the body 10 at the lower end of the fuel passage 13 to control said passage. under side the ball valve 16 seats, as at 18, on a tubular element 19. .T he said element At the 19 has an axial bore 20, and at the upper end thereof aftransverse fluid passage. 21 is formed in communication with the interior or valve chamber of the cap 11 anduwith an axial bore 20 in said element 19.

The lower end of the cap 11 has a jet orifice 22 formed axially therein, the upper end of which preferably flares as at 22*. Surrounding the shank 21 of the element 19' is a compression spring 23 which bears at its lower end against the-cap 14; at the interior adj acentto the jet orifice 22, and abuts at its upper end against a shoulder formed at the base of the shank 21.

'ith the described construction, at each feed stroke of the'pump fuel will. be forced through the passage 13 of the body 10 and the pressure will unseat the valve 16. thereby admitting the fuel around the said ball valve and permitting the same to pass through the passage 21 and axial bore 20 and outward through the jet orifice 22. The;

movement of the valveis limited by an endescribed n zzle. the predetermined quantitv of fuel is unfailingly delivered and the.

valve instantly closed so that the regulation of the valve isinsurcd .with respect-to both its rapm-ity-ainl the period of its operation llaving thus described my invention I claim as new. and desire tosecu re by Letters Patent: 1 I
